Changes
- Show an app launch screen and refine App Hall cover handling.
- Report private app storage usage. Default quotas are now 16 KiB per AppId and 4 KiB per value, with up to 16 keys. Updating an installed app preserves its data; explicit uninstall clears it.
- Migrate Host network settings out of app storage, with retry-safe migration handling.
- Read image sections through bounded buffers and validate their contents; update SPI NAND sector caching and invalidation.
- Use a quadratic device master-volume curve and adjust the ESP-Mosaico display path.
- Include updated factory applications and SDK 0.20.1 gamepad behavior. Host-only updates preserve installed Bundles.
Validation and limitations
GitHub Actions passed all five Host builds, shared Linux Host regression, dual-architecture factory app builds and verified image assembly. SDK Windows installation and public download checks passed. Local Host regression, Guest conformance builds, format/architecture checks, 140 Python tests (one skipped), and S31 Host compilation passed. Hardware display/launch checks, volume A/B listening and task minimum-free-stack measurements remain outstanding. No new hardware acceptance or measured performance improvement is claimed. ESP-Mosaico and ESP32-S3 board support retain their preview status.
